To 'all'whom it may concern:

Be it known that I, BENJAMIN F. MAYp, of Salem, county of Essex, Stateof Massachusetts, have invented an Improvement in Raceways forNail-Asserting Machines, of which the following description, inconnectionwith the accompanying drawings,'is a specification, likeletters on the drawings representing like parts.

In machines for assortingjnails the nails laid in grooves of.thejracewayfheadsand' points indiscriminatelyare led to apparatus forinsuring the delivery of saidnails with their heads or pointsall in onedirection.

way of discharging from the raceway-grooves imperfect nails or sliversof metal.

This invention has for its object an improved construction of theraceway and grooves, whereby any small nails or slivers may bedischarged before arriving at the end of the raceway.

In accordance with my invention I-provide each raceway-groove with atapered slot arranged in the generaldirection of the length of andpreferably substantially coinciding for a part or the whole of itslength with said groove, said slot being of a length preferably a littlegreater than the length of the nails to be assorted, the narrowest partof each of said slots being represented as extended-upwardly inthedirection of the length of the groove, one end (herein represented asthelowerend) of each of said slots beingprovided, preferably, with an.enlarged opening."

Figure l, in plan'view, shows part of a raceway provided with myimprovements; Fig. 2, a section thereof in the dotted line at, and Fig.3 a partial cross-section in the line m.

The metallic bed or plate A, as herein shown, has a series ofgrooves a.made in rising portions of the plate, and-the face of the bed betweenthe said grooves is concaved as at b, the lower ends of the concavedspaces being providedwith open spaces b", through which may drop anynails thrown on the raceway-plate which do not enter the racewaygrooves(11.. Each groove ais provided with a tapered S1013-Ct' and, as shown,with a hole through the; groove in: the general direction of itslength'and preferably so as to substancIaim as new, and desire to secureby-Letters Serial No. 681,612. (No model.) J

- a I The wider part of a the slot starts at the 111016 a and, as hereinrepresented, is carried toward the upper end of*the plate, and the slotis-i preferably longer than the length of the nails* to:be assorted,saidslot being cut tially coincide fora partjof 2 its} lengthwith saidgroove, the slot shown beingrepresented as removing more stock from onethan from theother; side wall of the groove. With this slot in' thegroove any perfectnails of a diameter greater than the width ofthe slot,whether head or point first, ".will readily pass the hole a but it asilver smalleror shorter than the regular nails being assorted comes inposition above said slot'said sliver immediately drops into and throughsaid slot into a suitable receptacle 0, located below the plate A. Whenthe smaller end of the sliver leads, it will drop through the slotimmediately, as shownby dotted-line's, Fig. 2, while if the larger endof the sliver leads it will not drop until the said largerend arrivesabove the hole a The hole a is of a diameter greater than the width ofthegroove.

At the 1eftin Fig..1 I have shown a series of nails of proper sizerunning down the raceway-groove.

Having described my invention, what I Patent, isl 1"." A racewaypresenting a groove provided in its bottomwith an uncovered slotarranged in the'general'direction of said groove, said slot being longerthan the nail being handled.

A raceway having a groove provided with a slot arranged in thegeneral direction of said groove,with an enlargement at the end of saidslot, said slot being longer than the nail being handled. a a 9 3. Araceway having a groove provi ed'with a slot arranged in the generaldirection of said groove, and .with an enlargement at the-end of saidslot.

6. A raceway having a groove, and a tapering slot made therein in thegeneral direction of the length of said groove, said slot removing morestock from one than from the other side of said groove.

7. A raceway having a groove provided with a slot arranged in thegeneral directionof the groove, and ahole intersecting said slot, saidhole being of greater diameter than the Width of the groove and locatedin the bottom of said groove.
